• Diabetes is a disease derived from multiple causative factors. It is characterized by elevated levels of plasma glucose (hyperglycemia) in the fasting state or after administration of glucose during an oral glucose tolerance test.
• type 1 diabetes or insulin-dependent diabetes mellitus (IDDM)
• IDDM insulin-dependent diabetes mellitus
• T2DM noninsulin-dependent diabetes mellitus
• insulin is still produced in the body, and patients demonstrate resistance to the effects of insulin in stimulating glucose and lipid metabolism in the main insulin-sensitive tissues, namely, muscle, liver and adipose tissue.
• T2DM noninsulin-dependent diabetes mellitus
• T2DM noninsulin-dependent diabetes mellitus
• These patients often have normal levels of insulin, and may have hyperinsulinemia (elevated plasma insulin levels), as they compensate for the reduced effectiveness of insulin by secreting increased amounts of insulin.
• GDIS glucose-dependent insulin secretion
• GPCR G-protein coupled receptors
